Abstract

Provided is a method of manufacturing a wire with a terminal, the wire with a terminal including a wire, a metal terminal, and a sealing member obtained by curing an anti-corrosive material, the method using a manufacturing apparatus for the wire with a terminal including a transparent mold including a cavity portion, and a protruding portion that protrudes into the cavity portion, the method including an introducing step of placing, in the cavity portion, a non-sealed wire with a terminal before including the sealing member including the wire and the metal terminal, and introducing the anti-corrosive material into the cavity portion; and an irradiating step of irradiating the anti-corrosive material in the cavity portion with ultraviolet light through the transparent mold.

First claim

What is claimed is:

1. A method of manufacturing a wire with a terminal using a manufacturing apparatus, the wire with a terminal comprising: a wire including a conductor and a wire covering member configured to cover the conductor; a metal terminal connected to the conductor of the wire; and a sealing member configured to cover a joint between the conductor and the metal terminal, the sealing member being formed by curing an anti-corrosive material, the method comprising:
providing the anti-corrosive material, the anti-corrosive material including: an ultraviolet curable resin comprising a polymerizable compound including at least one of a photopolymerizable (meth)acrylate monomer or a photopolymerizable (meth)acrylate oligomer, the polymerizable compound includes a combination of a monofunctional (meth)acrylate monomer and a bifunctional (meth)acrylate monomer, or a combination of at least one of a monofunctional (meth)acrylate monomer or a bifunctional (meth)acrylate monomer and at least one of a trifunctional (meth)acrylate monomer or a polyfunctional (meth)acrylate monomer having four or more functional groups;
providing the manufacturing apparatus, the manufacturing apparatus comprising: a transparent mold including a cavity portion formed by overlapping a first transparent mold member and a second transparent mold member with each other, the cavity portion configured to accommodate the joint therein and allow the anti-corrosive material to be introduced thereinto; and a protruding portion that protrudes from the transparent mold into the cavity portion and restricts flowing of the anti-corrosive material;
placing in the cavity portion of the transparent mold of the apparatus a non-sealed wire with a terminal including the wire and the metal terminal without the sealing member, and introducing the anti-corrosive material into the cavity portion under a state in which the protruding portion protrudes into the cavity portion; and
irradiating the anti-corrosive material in the cavity portion of the transparent mold of the apparatus with ultraviolet light through the transparent mold.

2. The method of manufacturing a wire with a terminal according to claim 1 , further comprising removing the wire and the terminal from the transparent mold to form the wire with the terminal and the sealing element, wherein the removing includes separating the protruding portion and the transparent mold from each other.
